Okay so I'm curious about the radar ability, do they just run to the items like the treasure hunter? Dunno if its just me but that seems kind of like a silly skill unless they actually fetch them because its easy just walking around and clicking on the items..Am I missing something here? I'm level 13 I think so I have bit before I can check it out.

Good question. I've found radar to be quite useful on mobile or other small screens. When you join a room that has things to scavenge, you will get an icon that looks like this:

it will appear at the edges of the screen so you can see where there's something to pick up. It actually makes it quite a bit faster to scavenge cause you can just go straight to it instead of wandering.Later at level 27 you are supposed to be able to see what the item is instead of just the ? bubble.

I've noticed the same. I think it's a chicken change and not a degrading eggs thing since I am now gathering brown eggs from my chickens instead of gold... I'll change it for now and if it looks like I need to modify it later, I'll do it again.
